Abstract
A gliding bed for a concrete slab comprises a first film and a second film wherein the first film can be brought into contact with a foundation of the concrete bottom slab and the second film can be brought into contact with a bottom side of the concrete slab by pouring concrete onto the second film and which films are tightly connected to each other at edges. In order to minimize friction between the concrete slab and the foundation, at least one gas- and liquid-permeable layer formed from a fleece and/or a textile fabric, a woven fabric or a knitted fabric is provided between the films.
